title: Antiproliferative effect of dietary glucarate on the Sprague-Dawley rat mammary gland.
abstract: Dietary glucarate has previously been shown to inhibit chemical carcinogen-induced rat mammary tumorigenesis. It is demonstrated in this paper that in the mammary gland of the female Sprague-Dawley rat, feeding glucarate at a dose of 70 mmol/kg AIN76A diet for 2 weeks beginning at 35 days of age, markedly reduces [3H]thymidine labeling. Specific histochemical staining for beta-glucuronidase is used to show that the glucarate diet fed to rats for 2-4 weeks inhibits beta-glucuronidase activity in the mammary gland and has a marked antiproliferative effect on mammary epithelium. Glucarate may inhibit rat mammary carcinogenesis, in part, by changing the proliferative status of the target organ.
